Manage your own digital aquarium in various relaxing environments. Raise fish with unique behaviors, decorate tanks, and unlock rare species. Whether you enjoy min-maxing your income, unwinding with a cozy game, or you’re a fish lover looking for a digital tank, you’ll find it in Fish Tank Simulator

















Mainly due to the fact that the:
- Art style is not yet decided, the UI is temporary or incomplete.
- Performance is not yet fully optimized.
- Core gameplay loop is not final, however it's complete and playable. It's just that gameplay-enhancing features are planned to be added. (Relaxing Fishing for example is planned to fill the wait time)
- Balance is not finalized. Still looking to get feedback on coins and XP numbers to better balance the game.

FTS is a game made by a solo developer, created on October 8th, 2025. It’s my 4th game attempt after 3 years of game development. The main inspiration was a Facebook game I loved called Fishville. However, that game wouldn’t work well as an offline, session-based game, so I added more features over time, and it became its own standalone title.
If you have any questions or would like to provide feedback, I’d greatly appreciate it, just join the Discord and share your thoughts there. I genuinely hope you enjoy my game from the bottom of my heart!
More will be described as the development process progresses.
